LATCH.

SPECIFICATION forming part of Letters Patent No. 639,515, dated December19, 1899.

l Application iiled May 31, 1899. Serial No. 718,851, (No model.)

T all whom, t may concern:

Be it known that I, CHARLES BROWN, a citizen of the United States,residing at Lightsville, in the county of Darke and State of Ohio, haveinvented a new and useful Latch, of which the following is aspecification.

My invention relates to latches; and it has for its object to provide alatch which is particularly adapted for application to a barndoor orother heavydoor and which may be disposed upon the door in any relationthereto, as may be desired.

A further object of my invention is to provide a durable and neatarrangement of bearings for the latch-lever which may be easily andquickly adjusted and which will be effective in their operation.

The invention consists of a spring-pressed bolt adapted to engage akeeper, and which keeper has a downwardly-curved lip extending in thedirection of the bolt and which will act to press the bolt backwardlywhen the door is closed.

Extending from the bolt-casing and rearwardly thereof iis a handlehaving an opening adjacent the casing for the passage of the rear end ofthe bolt. From the rear end of the bolt extends a flexible connection toa latch-lever, which lever is passed through a slot in the door and hasbearings in the inwardly-extending ears of plates arranged one at eachside of the latch-lever. The handle, which extends over the latch-leverat the outer side of the door, forms a guard for the lever, while aspring is arranged upon the bolt to hold it normally distended.

In the drawings forming a portion of this specification, Figure l is aperspective view showing my invention as applied to a door, and Fig. 2is a section on line 2 2 of Fig. 1.

Referring now to the drawings, I provide a bolt 5, adapted to bereciprocated in a casing 6, and which latter has outwardly-extendingflanges 7, through the medium of which it is secured to the face of adoor 8. The rear portion of the bolt 7 is reduced in transverse section,as shown at 9, and upon this reduced portion is disposed a helicalspring 10, which bears at one end against the shoulder which forms oneterminus of the reduced portion. The opposite end of the spring 10engages a washer 11 upon the reduced portion 9 of the bolt, and whichwasher lies against the inwardly-directed shoulder 13a upon the innerface of the casing.

The rear end of the bolt 5 is perforated, as shown, and through thisperforation is passed a flexible connection 13, the opposite end ofwhich is passed through a perforation 14 in the latch-lever 15, whichlatter has trunnions 16, having bearings in the ears 17 of plates 18,which are disposed upon the face of the door 8 and at each side of aslot 19, formed therethrough, the ears 17 lying in similarlyformedrecesses in their respective faces of the slot 19. The end of the levercontaining the perforation 14 is extended upwardly a suitable distanceand is provided with a finger-grip 20, as shown, the opposite end ofsaid lever extending through the slot 19 and in a direction away fromthe bolt 5 and forms a means on the opposite side of the door from thebolt for withdrawing the latter.

The combined handle and guard 21 has one end bifurcated to form legs 22and 23, which are disposed at opposite sides ot' the rear end of thecasing 6 and engage the flanges 7. Common retaining-screws are passed through alining perforations in the legs 22 and 23 and the flanges 7, asshown, said screws entering the material of the door S. The handle 21curves outwardly and then inwardly over the lever 15 and forms a guardtherefor, the rear end of the guard being secured to the doorfacethrough the medium of the screw or bolt, as shown. It will be noted thatthe interspace between the legs 22 and 23 forms a passage for the bolt5.

In connection with my latch I employ a keeper comprising a U-shapedplate 24, having outwardly-extending flanges 25 at its ends, and whichlatter are perforated for the reception of attaching-screws,as shown.The

,edge ofthe web 26 of the plate adjacent the bolt 5 is curved outwardlyand downwardly, as shown, to form an abutting flange 27 which in theoperation of closing the door receives the direct engagement of thetapered end 2S of the bolt 5, and thus acts to throw the bolt againstthe tendency of the spring 10 in the usual manner.

It will be readily understood that I may em- IOO ploy my latch whereverit is applicable, and also that I may vary the specific construction andarrangement herein shown and that I may use Whatever material may bedeemed expedient in the manufacture without depart ing in any way fromthe spirit of my invention.

Having thus described the invention, what is claimed is* l. A latchcomprising a bolt and its casing, a latch-lever connected with saidbolt, trunnions carried by the latch-lever, plates hav- 1lng bearingstherein receiving the tru unions, a handle connected with said casingand extending over the lever, and a keeper for said bolt.

2. The combination with a door and its casing, said door having a slottherein, of a latch comprising a bolt and its casing, plates adjacent tothe slot in the door and having ears lying in recesses in the face ofthe slot, bearings in said ears, a latch-lever having trunnions disposedin said bearings, said lever passing entirely through said slot,connections between the lever and bolt, a handle connected with thebolt-casin g and extending over the latch-lever, and a keeper for thebolt.

The combination with the door and its casing, said door having a slottherethrough, of a bolt having a casing, plates connected with the doorand having ears lying in recesses in the face of said slot, bearings insaid ears, a latch-lever passed through said slot and having trunnionsdisposed in said bearings, connections between the lever and the bolt, ahandle having a bifurcated extremity within the slot of whichbifurcation the boltcasing is disposed, connections between saidbifurcations and the bolt-casing, and a keeper having an outwardly anddownwardly extending flange projecting in the direction of the bolt andover which the bolt is adapted to slide.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

CHARLES BROWN.
